CHURN.

Specification of Letters Patent.

Eatented Jan. 1, 1907.

Application filed August 1, 1906. Serial No. 328,701-

To all whom it may concern:

Be it known that I, EUGENE L. ALLEN, a citizen of the United States, residing at Springfield, in the county of Sang-anion and State of Illinois, have invented certain new and useful Improvements in Churns, of which the following 1s such a full, clear, and exact I I l I l l l i l l B, having screw-threaded parts 5, extend through the plate A and the angleplates A Nuts b fit on the parts I) of the rods B and when screwed up tightly against the plates A and A bind them firmly together. A

cushion 5 of rubber or other yielding madescription as will enable-others skilled in the 1 art to which it appertains to make and use my said invention.

This invention relates to oscillative churns.

The purposes of the invention are to provide a frame which shall be neat and attractive in appearance and at the same time have suflicient stability to prevent displacement of the churn while in operation, to provide an oscillative cradle adapted to support the churnbody, to provide improved means for connecting the cradle with the main frame, to provide simple and effective means to limit the oscillations of the cradle, to pro vide an adjustable handle in connection with the cradle, to provide means for ro. 'tatmg the churn-flasher, and to provide a simple and effective coupling for connecting the dasher with the shaft which operates the Same.

- With these ends in view my invention consists in the novel features of construction and combinations of parts shown in the annexed drawings, to which reference is hereby made, and hereinafter particularly described and finally recited in the claims.

Referring to the drawings, in which similar reference-letters designate like parts in the several views, Figure 1 is a perspective view of the churn. Fig. 2 is an enlarged partial vertical section on the line 2 2 of Fig. 1. Fig. 3 is an enlarged perspective view of the coupling. Fig. 4 is a transverse section through the coupling on the line 4 4 of Fig. 3. Fig. 5 is a vertical axial section through the churn, and Fig. 6 is an enlarged perspective View of the adjustable handle and the cog-pinion and adjacent parts.

The base of the main frame comprises side pieces A, having bosses a, and end pieces A, having integral blocks a, serving as feet and having weight sufficient to give stability to the structure. Gas-pipes A screw into the bosses a. Angle-plates A have lugs a fitting partially around the pipes A A single bolt (Jr/passes through each of the platesA and connects them with the pipes A respectively. An elliptical plate A is secured to the angleplates, as will now be described. Bent rods terial, is secured on each of the rods B. The rods B serve the doublepurpose of connecting the plates A and A and supporting the bumpers b and may be turned to change the position of the bumpers so as to increase or diminish the swing of the cradle. Bolts a extend through the plates A and A and strengthen the connection of the plates with each other. A toothed segment-plate A is secured on the plate A, but may be made integral therewith without departure from my invention. The cradle has converging side pieces D connected together at the top and connected to a circular base plate D. Horizontal bars D and D connect the side pieces D. The churn-body E is supported on the base-plate D. The dasher E is secured to the vertical shaft E which is axial to the churn-body and turns in a central bearing 6 at the bottom of the churn-body. The dasher E is preferably a sheet of aluminium, having angular perforations e and circular perforations 6 During the oscillating of the cradle the pinion F, running on the rack-bar A causes the dasher to turn alternately to the right and the left, and the turning of the dasher causes the cream to flow to and fro through the perforations c and 6 thereby breaking pediting the production of butter.

A vertical shaft F in line with the shaft E turns in bearings in the cross-pieces D and D A cog-pinion F, secured on the shaft F, meshes with the teeth of the segment-plate A A bracket 1), secured on the bar D supports a roller F which turns in contact with the back of the plate A and prevents the cradle from swinging away from the plate A. A bar G has a longitudinal slot g and has at its end sockets g, adapted to receive a handle G, fitting in the sockets. A bolt G passes through the bar D and through the slot in the bar G, and the bolt connects the bar G with the bar G so that by loosening the nut on the bolt the bar G may be turned into different positions, as indicated by dotted lines in Fig. 1, or may be slid to the right or to the left, as may be desired, to increase or diminish the leverage and place the handle G in the most conven- IIO ient position for use. The handle G may be used on either side of the machine. A sleeve E connects the shaft E with the shaft F. The sleeve E has a feather e fitting in a longitudinal channel f in the shaft F and also fitting in the longitudinal channel 6 in the shaft E. A collar 6 on the shaft E supports the sleeve E The shaft E extends upward into the sleeve E for a short distance and may be disengaged from the shaft F by sliding the sleeve upward on the shaft F far enough to release the upper part of the shaft E. When the sleeve E is slid upward, as described, the cover E may be removed, and the dasher E may be withdrawn from the churn-body. A block (1 is suitably secured to the upper ends of the side pieces D. A bolt D extends through the block d and the plate A and is provided with a nut d. A brace-rod A has a bent finger (1 extending through a hole in one of the side pieces, and the upper end of the rod extends through the bolt I) and is secured by a nut (f. A plate d secured to the side pieces D, connects the handle D with the cradle.

In the ordinary use of the churn if the operator is standing the cradle will be oscillated by moving the handle D to and fro, and the bumpers b will prevent excessive oscillation of the cradle. The striking of the side pieces D against the bumpers causes sudden stoppage of the oscillations of the cradle, which serves to agitate the cream in the churn-body, and thereby render more effective the opera tion of the churn. If the operator wishes to shorten the oscillations, he will loosen the nuts and turn the bumpers toward the cradle, or if he wishes to lengthen the oscillations he will move the bumpers away from the cradle, and when the bumpers are set he will tighten the nuts to secure them in the desired position. If the operator wishes to sit while operating the churn, the lateral handle G, fitting in the sockets of the bar G, will be used, and the bar will be set at such inclination and with such leverage as may suit the convenience of the user.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A churn-frame comprising side pieces,

end pieces having heavy feet, and vertical frame members secured on one of the side pieces; in combination with an oscillative iradle mounted on said vertical frame memers.

2. The combination of side pieces, weighted end pieces secured to said side pieces, vertical standards, a'segment-plate secured on said standards, a cradle mounted to oscillate on the segment-plate, a vertical shaft mounted on the cradle and having a longitudinal channel, a pinion secured to said shaft and meshing with the segment-plate, a churnbody supported on the cradle, a revoluble dasher-shaft having a longitudinal channel and a flange, and a sleeve fitting around both shafts and having a feather fitting in the channels of both shafts.

3. The combination of a main structure, standards on the main structure, cornerplates secured to said standards, a segmentplate secured to said corner-plates, a pivotal bolt extending through the segment-plate, a cradle oscillative on the pivotal bolt, and a brace-rod connecting the pivotal bolt with the main structure.

4. The combination of a main frame, standards secured thereon, brackets secured to said standards, a segment-plate, an oscillative cradle mounted on the segment-plate and turnable rods having threaded parts extending through and connecting the segment-plate and the brackets and havingplushions limiting the oscillations of the cra- 5. The combination of a main frame, an oscillative cradle supported on the main frame, a slotted bar provided with sockets and connected with the cradle and a handle adapted to fit in the sockets of said bar.

6. The combination of a main frame, a cradle oscillative on the main frame, and bumpers adjustable to change the scope of the oscillations of the cradle.

In witness whereof I have hereunto subscribed my name, at Springfield, Illinois, this 28th day of July, 1906.

EUGENE L. ALLEN.
